Numbers 5:15-17

New Revised Standard Version, Anglicised

¹⁵ then the man shall bring his wife to the priest. And he shall bring the offering required for her, one-tenth of an ephah of barley flour. He shall pour no oil on it and put no frankincense on it, for it is a grain-offering of jealousy, a grain-offering of remembrance, bringing iniquity to remembrance.

¹⁶ Then the priest shall bring her near, and set her before the Lord; ¹⁷ the priest shall take holy water in an earthen vessel, and take some of the dust that is on the floor of the tabernacle and put it into the water.
